I've never heard anyone complain about filling the stratosphere with metal oxides, do you have somewhere I can read more about this risk? Naively, I would have expected that even thousands of 250kg satellites would be insignificant on the scale of the whole stratosphere (we're not talking about surface-level CO2, where we're pumping out gigatons per year), but I have no idea what that ecosystem is like. Is the metal oxide concentration measurable?

I do think this is a temporary issue; once the cable ISP monopolies are no longer valuable because anyone can just get Starlink, that competitive pressure will push down hard on those cable monopolies and infrastructure laws will have to return to sanity. Terrestrial ISPs with fiber-sharing requirements and appropriate infrastructure build-out could absolutely out-compete Starlink, but right now they can just collude together and lobby against changing the status quo.

I would much prefer to have a functional bureaucracy and intelligent, efficient infrastructure! But it's probably easier to fix that by launching the largest satellite constellation ever than by playing politics against some of the wealthiest media companies on the planet.
